The goal of grib is to read GRIB and GRIB2 files. Right now it does pretty much nothing and is proof-of-concept only.
You can install the development version from GitHub with:
# install.packages("remotes")
remotes::install_github("paleolimbot/grib")This is a basic example which shows you how to solve a common problem:
library(grib)
grib2_info("~/Desktop/CMC_hrdps_maritimes_PRATE_SFC_0_ps2.5km_2020091400_P001-00.grib2")
